Hashtag Jakarta EE #56

Sunday, January 24, 2021 - 05:59 by Ivar Grimstad

Welcome to the fifty-sixth issue of Hashtag Jakarta EE!

It is time for a new edition of Studio Jakarta EE LIVE! This time I have Emily Jiang from IBM with me in the studio. We will talk about MicroProfile 4.0 and I am pretty sure that Emily will show some cool demos as well.

Check out microprofile.io for details about MicroProfile 4.0 and MicroProfile in general. And of course, make sure to tune in to Studio Jakarta EE LIVE: MicroProfile 4.0 on Thursday!

MicroProfile 4.0 contains updates to all the specifications. It is based on the Jakarta EE 8 versions of the four specifications that form the foundation of MicroProfile. This means that it is still on the javax.* namespace.

How difficult the migration from the javax.* to the jakarta.* namespace is for your particular use case depends on the complexity of your application. The focus has mainly been on the Java package names, but there are some other areas that may require some effort as well. Check out my Migration Guide for an example of how to migrate an application that touches most of the areas.

Please reach out to me if you discover areas that I have missed in the guide. I will be happy to update it!

There is only one more stop planned on the Jakarta EE Virtual Tour. We really enjoy giving these talks, so please reach out if you are interested in hosting us at your JUG or MeetUp.
